[PATCH 4/4] scsi: scsi_transport_spi: constify attribute_group structures.

[Arvind Yadav <arvind.yadav.cs@xxxxxxxxx>]

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/attribute_container.h>
and <linux/sysfs.h> work with const attribute_group. So mark the non-const
structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  15444	   1616	      0	  17060	   42a4	drivers/scsi/scsi_transport_spi.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  15572	   1488	      0	  17060	   42a4	drivers/scsi/scsi_transport_spi.o
